<h3 id="之前的做法">之前的做法</h3>
<p>在 Docker 17.05 版本之前，我们构建 Docker 镜像时，通常会采用两种方式：</p>
<h4 id="全部放入一个-dockerfile">全部放入一个 Dockerfile</h4>
<p>一种方式是将所有的构建过程编包含在一个 <code>Dockerfile</code> 中，包括项目及其依赖库的编译、测试、打包等流程，这里可能会带来的一些问题：</p>
<ul>
<li>
<p>镜像层次多，镜像体积较大，部署时间变长</p>
</li>
<li>
<p>源代码存在泄露的风险</p>
</li>
</ul>
<p>例如，编写 <code>app.go</code> 文件，该程序输出 <code>Hello World!</code></p>
<div class="highlight"><pre class="chroma"><code class="language-go" data-lang="go"><span class="kn">package</span> <span class="nx">main</span>

    <span class="nx">fmt</span><span class="p">.</span><span class="nf">Printf</span><span class="p">(</span><span class="s">&#34;Hello World!&#34;</span><span class="p">);</span>
<span class="p">}</span>
</code></pre></div><p>编写 <code>Dockerfile.one</code> 文件</p>

</code></pre></div><h4 id="分散到多个-dockerfile">分散到多个 Dockerfile</h4>
<p>另一种方式，就是我们事先在一个 <code>Dockerfile</code> 将项目及其依赖库编译测试打包好后，再将其拷贝到运行环境中，这种方式需要我们编写两个 <code>Dockerfile</code> 和一些编译脚本才能将其两个阶段自动整合起来，这种方式虽然可以很好地规避第一种方式存在的风险，但明显部署过程较复杂。</p>
